College years are cool and full of fun! That’s why many of us don’t think of graduation but when it’s time to wear a cap flask, enjoy it! But do you have such a flask ready? If you don’t, let’s make it, you’ll need some simple tools, velcro, bobby pins, and booze. Just pop off the top button with a pair of pliers, Velcro in the bladder, secure the whole mess with bobby pins and drink up. A great and simple craft, a perfect thing to be there and remember this day for long!
